Approximately one in two older adults living in long-term care (LTC) settings sustains a fall every year, resulting in significant human suffering and treatment costs. The complex set of factors that contribute to fall risk among this population demands a multidisciplinary approach to this problem, with physicians playing a pivotal role in risk assessment, prevention, and management. We describe a study where facility personnel from five LTC sites were trained in the use of a standardized surveillance tool to track falls, fall injuries, and contributing factors over 16-months. Using a pre-/post-test design, interventions included a multidisciplinary, evidence-based approach to fall risk assessment and monitoring, environmental modifications, exercise, and education strategies. Interventions by a multidisciplinary team, including physicians, were successful in reducing fall-related injuries and relatively successful in reducing the rate of falls among LTC residents. Further study is needed over a longer period of time, using a randomized control trial, to determine the effectiveness of specific interventions and to generalize findings to the larger population of LTC residents.
Key words: fall prevention, long-term care, multidisciplinary approach, older adults.

The ultimate aim of critical appraisal is to decide whether the conclusions of an article are helpful in the prevention or management of illness in your patients. This requires the article to be relevant to your practice and to contain sufficient information to determine if the conclusions are supported by the evidence within it. We offer approaches to the appraisal of different types of publications addressing primary and secondary prevention.
Key words: prevention (primary, secondary), clinical research, critical appraisal, clinical practice guidelines.

Preventive health interventions are key to maintaining the health and good function of older adults. Despite being safe and a highly effective method of preventing certain infectious diseases, vaccination rates among older adults continue to lag behind national goals. Vaccines for older adults can be divided into three categories: those that are required for all older adults, those that may be required for special circumstances, and those that are required for travel. Physicians should be familiar with the indications, contraindications, and adverse effects of commonly used vaccines among older adults. This article will focus only on the vaccines required for all older adults.
Key words: vaccines, older adults, influenza, pneumococcal vaccine, herpes zoster, tetanus.

Differentiating between Parkinson’s disease dementia (PDD) and dementia with Lewy bodies (DLB) is a difficult issue for many clinicians. To date, these diseases share most of their clinical, neuropathological, and management features. Therefore, PDD and DLB are considered by some authors to be the two extremities of a single spectrum disease named Lewy body diseases. Nevertheless, specific diagnostic criteria now exist for each disease and specific diagnosis remains of interest in clinical practice. In this article, we summarize features and diagnostic criteria of both PDD and DLB, compare them, and examine their treatment options.
Key words: Parkinson’s disease dementia, dementia with Lewy bodies, Lewy body disease, movement disorders, dementia, treatment.

Dyspepsia is defined as an epigastric pain or discomfort thought to originate in the upper gastrointestinal (GI) tract. There is discussion, especially in uninvestigated patients, about whether gastroesophageal reflux disease (GERD) can be separated from dyspepsia. If heartburn and regurgitation are the dominant symptoms, GERD is the likely diagnosis. Among older adults, more severe esophagitis is often seen, while at the same time patients report less severe symptoms. The use of nonsteroidal anti-inflammatory drugs (NSAIDs), acetylsalicylic acid (ASA), and cyclo-oxygenase 2 selected inhibitors is associated with an increased frequency of dyspepsia and, more importantly, ulcers and upper GI bleeding. In new-onset dyspepsia among older adults, endoscopy should be considered given the increased risk of an upper GI malignancy. Among individuals taking NSAIDs, the medication should ideally be discontinued if it is thought to be the cause of dyspepsia. For NSAID prophylaxis, there is evidence that use of a once-daily proton pump inhibitor or misoprostol 200 µg two to four times per day decreases the risk of upper GI ulcers. NSAID prophylaxis is underused among older adults taking non-ASA NSAIDs, and the reasons for this and its consequences require further study.
Key words: dyspepsia, gastroesophageal reflux disease, NSAIDs, ASA, H. pylori.

The aging of the population and increasing prevalence of diabetes are worldwide phenomena that require a better focus on challenges of diabetes management in older adults. We now understand the benefits of tight glycemic control and have an armament of agents to achieve such a feat. However, in an aging population, balance must be sought between the goals of glycemic control and those of overall health status, including quality of life. Insulin therapy, in particular, requires significant self-care abilities. Insulin therapy can be used safely and effectively if diabetes management plans are formulated with consideration of the clinical, functional, and psychosocial contexts of an older adult.
Key words: diabetes, older adults, insulin therapy, geriatrics, glycemic control.

Dyspnea is among the most frequent complaints among older adults. The prevalence of comorbid medical conditions combined with physiological changes of aging present significant challenges to the diagnosis. The initial approach to the older adult with dyspnea mandates consideration of a broad range of diagnoses. Failure to consider life-threatening medical conditions presenting with dyspnea, such as pulmonary embolism, acute coronary syndromes, congestive heart failure, asthma, obstructive pulmonary disease, pneumothorax, and pneumonia, can lead to significant morbidity and mortality. This review focuses on the rapid assessment and approach to the older adult with acute dyspnea.
Key words: dyspnea, shortness of breath, approach, geriatric, older adults.

Cerumen, or earwax, is the product of the sebaceous and ceruminous glands combined with débrided epithelial cells and hair from the external auditory canal. Cerumen is usually extruded by a combination of jaw movements from chewing and speech, and natural epithelial migration. However, cerumen may become impacted, especially among older adults and individuals with mental retardation. Cerumen impaction may cause hearing loss, otitis externa, vertigo, tinnitus, or cough. There are multiple methods for removing earwax, with limited evidence to support any of the current practices. Irrigation or manual disimpaction using a curette have long been the accepted earwax removal methods, yet neither has been subjected to comparative trials with other methods. Irrigation alone is effective in up to 70% of cases of impacted cerumen. Ceruminolytics or eardrops are effective in up to 40% of cases without irrigation, and when combined with irrigation can be effective up to 97%. Cotton ear buds and ear candling should be avoided.
Key words: cerumen, earwax, irrigation, ceruminolytic, impaction.

Diabetic retinopathy (DR) remains the leading cause of vision loss and blindness in people of working age, in spite of the fact that current treatments are effective. Vision loss occurs in DR due to the development of maculopathy, especially diabetic macular edema, and due to proliferative diabetic retinopathy. Vision loss due to DR is preventable with the appropriate monitoring and timely treatment. Improved patient and health professional, education to encourage tight control of blood glucose and other systemic factors, and the establishment of readily available and appropriately timed eye examinations are necessary steps to further reduce visual impairment of people with diabetes.
Key words: diabetic retinopathy, vision loss, macular edema, neovascularization, laser photocoagulation.

Cataract surgery is the most common refractive surgical procedure performed on aging individuals. Major advancements in surgical and lens technology have led to enormous increases in surgical volume because of the improved safety profile and outcomes. Current research holds the potential for restoring full vision, including accommodation, without the need for glasses in the near future.
Key words: cataract, lens, refractive, vision, phacoemulsification.
